FIELD OF THE INVENTION
The invention provides compositions and methods for the multiplex analysis of biological samples prepared from formalin-fixed tissue specimens.
For over a hundred years, public and academic medical universities and institutions, pathology clinics, private biomedical institutions, tissue archives, hospitals, and museums have been preserving biological specimens with formalin and other chemical fixatives such as formaldehyde and ethyl alcohol. The most common fixative is formalin. Formalin is used as a fixative because of it superior ability to preserve both tissue structure and cellular morphology. This has resulted in the wide use of formalin for the successful preservation of histologic sections for traditional microscopic analysis. Formalin fixation is so effective in preserving tissue structure and cellular morphology that the formalin archive is a veritable treasure trove containing millions of samples. Within this archive are biological samples of healthy tissue, tissue samples from virtually every known human disease, and a multitude of preserved life forms.
Formalin fixation occurs through the cross-linking of proteins within the biological specimen. These protein cross links, while providing excellent cellular morphology preservation, also renders the fixed sample relatively insoluble. Because of these protein cross-links, the types of assays that can be performed on a formalin-fixed sample are limited in number, unable to provide quantitative results and lack sensitivity. In fact, formalin fixed biological samples are virtually unusable in many modern assay techniques, which are both highly quantitative and sensitive.
Thus, there is an unmet need in the industry to use histologically processed samples to generate preparations from these samples that contain subsets of biomolecules contained in the samples, and to combine these subsets to generate a library containing the entirety of the biomolecular components of a given histopathologically processed biological sample.
SUMMARY OF THE INVENTION
In general, the present invention relates to detection of diseases such as cancer by analysis of proteins contained in Liquid Tissue preparations obtained from histologically processed samples, such as formalin-fixed tissue.
In one aspect, the invention provides a method of generating a multiplexed Liquid Tissue preparation by contacting a first biological sample with a first buffer solution and a second biological sample with a second buffer solution, heating the first and second contacted samples at a temperature and for a time sufficient to substantially reduce the protein cross-links present in the biological samples, and treating the heated first and second samples with an effective amount of a proteolytic enzyme for a time sufficient to substantially reduce the proteins to individual peptides, thereby generating a multiplexed Liquid Tissue preparation. Detection comprises mass spectrometry (e.g., matrix-assisted laser desorption/ionization-time of flight mass spectrometry (MALDI-TOF), liquid chromatography electrospray ionization tandem mass spectrometry (LC-ESI-MS/MS), or surface enhanced laser desorption ionization (SELDI) mass spectrometry), immunohistochemistry, ELISA, Western blotting, polyacrylamide gel electrophoresis, synthetic aptamer binding analysis, or isoelectric focusing analysis.
In embodiments of the invention, the method also includes the step of detecting the presence of least one protein analyte in the first sample and at least one protein analyte in the second sample. In other embodiments, the first buffer is chemically distinct from the second buffer. In other embodiments, the method also includes the step of comparing the analytes detected in the first and second samples with one or more reference analytes; the reference analyte may be obtained from a subject having a disease or condition. Further, the invention provides the additional step of separating the first sample using a first separation system and separating the second sample using a second separation system, thereby generating a separated multiplexed Liquid Tissue preparation. The first separation system and the second separation system separately comprise a chromatography matrix. The first separation system may be distinct from the second separation system.
Optionally, the first biological sample and the second biological sample comprise adjacent serial sections.
The invention also provides the multiplexed Liquid Tissue preparation generated by these methods.
In another aspect, the invention provides a method of analyzing a tissue proteome by contacting a first biological sample with a first buffer solution and a second biological sample with a second buffer solution, heating the first and second contacted samples at a temperature and for a time sufficient to substantially reduce the protein cross-links present in the biological samples, treating the heated first and second samples with an effective amount of a proteolytic enzyme for a time sufficient to substantially reduce the proteins to individual peptides, and detecting the presence of at least one protein analyte in each of the first and second treated samples, thereby analyzing a tissue proteome. Optionally, the first biological sample and the second biological sample comprise adjacent serial sections.
In certain embodiments, the invention provides the additional step of separating the treated first sample using a first separation system and separating the treated second sample using a second separation system.
In other embodiments, the method includes at least n biological samples and n buffer conditions, wherein n is a positive whole number between 3 and 100.
In another aspect, the invention provides a kit for preparing a multiplexed Liquid Tissue preparation that includes a histopathologically processed biological sample, a buffer or buffer reagents, a proteolytic enzyme and one or more chromatography matrices. In some embodiments the kit also includes an additive or additive reagents.
In some embodiments, the histopathologically processed biological sample comprises a substantially homogeneous population of tissues or cells. The histopathologically processed biological samples are formalin-fixed tissue/cells, formalin fixed paraffin embedded (FFPE) tissue/cells, FFPE tissue blocks and cells from those blocks, or tissue culture cells that have been formalin fixed and/or paraffin embedded.
The methods of the invention also include the step of removing any paraffin or embedding compound in the histopathologically processed biological sample, such as by adding an organic solvent; heating; heating and adding a buffer; or heating and adding an organic solvent.
In other embodiments, the methods of the invention also include the step of mechanically disrupting the biological sample by, for example, manual homogenization, vortexing, or and physical mixing. In some embodiments the heating and/or proteolytic enzyme treatments are carried out in the presence of a reaction buffer such as Tris and/or ammonium bicarbonate, and generally has a pH in the range of about 6.0 to about 9.0. The buffer in some cases contains an additive such as glycerol, methanol, glycogen, or polyethylene glycol (PEG).
In other embodiments, the methods of the invention include the step of using a plurality of chromatography matrices to fractionate a single individual Liquid Tissue preparation into many different fractions based on the biochemical retention properties of the chromatography matrices. Each fraction is suitable for use in biochemical assays.
Generally, the proteolytic enzyme is proteinase K, chymotrypsin, papain, pepsin, trypsin, pronase, or endoproteinase Lys-C.
Mass spectrometry is a preferred means for detecting analytes contained in the Liquid Tissue preparations. MALDI-TOF, SELDI-TOF, LC-MS/MS, LC-ESI-MS/MS, and LC-FTICR-MS/MS are used to detect the presence or absence of one or more analytes in the Liquid Tissue preparations. The analytes can be, e.g., proteins or peptides derived from a protein.
The invention further provides methods of analyzing a plurality of multiplexed Liquid Tissue preparations by immobilizing a plurality of Liquid Tissue preparations on a support surface, such that each preparation is immobilized at a discrete location of the surface; contacting the support surface with a reagent of known binding affinity, and detecting the presence or absence of binding of the reagent of known binding affinity to the support surface. The plurality of Liquid Tissue preparations can be spotted into the support surface by manual spotting, ink-jetting, robotic contact printing, robotic non-contact printing, or piezoelectric spotting. The reagents of known binding affinity may be, for example, antibodies and antibody fragments, single domain antibodies, engineered scaffolds, peptides, nucleic acid aptamers, a receptor moiety, affinity reagents, small molecules, protein ligands, and the like. The support surface contains a material such as glass, derivatized glass, silicon, derivatized silicon, porous silicon, plastic, nitrocellulose membranes, nylon membranes, or PVDF membranes.
All the methods of the present invention provide for the fractionation or separation of the Liquid Tissue preparations prior to mass spectrometry or other detection means. Such a separation can include a matrix-based separation step. However, Liquid Tissue preparations can be prepared and analyzed without further separation prior to analyte detection or analysis.
Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. Although methods and materials similar or equivalent to those described herein can be used in the practice or testing of the present invention, suitable methods and materials are described below. All publications, patent applications, patents, and other references mentioned herein are incorporated by reference in their entirety. In the case of conflict, the present specification, including definitions, will control. In addition, the materials, methods, and examples are illustrative only and are not intended to be limiting.
These and other objects of the present invention will be apparent from the detailed description of the invention provided below.
BRIEF DESCRIPTION OF THE DRAWINGS
The foregoing and other features and advantages of the invention will be apparent from the following more particular description of preferred embodiments of the invention, as illustrated in the accompanying drawings in which like reference characters refer to the same parts throughout the different views. The drawings are not necessarily to scale, emphasis instead being placed upon illustrating the principles of the invention.
FIG. 1 is a flow chart illustrating the method to achieve a multiplexed plurality of unique Liquid Tissue biomolecule preparations simultaneously from a single biological sample of the present invention.
FIG. 2 describes the steps involved in FIG. 1.
FIG. 3 shows a base chromatogram analysis by mass spectrometry of one of two separate and distinct Liquid Tissue preparations from the same histopathologically processed biological sample for identification of similar and different proteins. This particular preparation was made by incubation and tryptic digestion in 100 mM ammonium bicarbonate buffer.
FIG. 4 shows a base chromatogram analysis by mass spectrometry of a second and distinctly different Liquid Tissue preparations from the same histopathologically processed biological sample as in FIG. 3 for identification of similar and different proteins. This sample was prepared using the same buffer as the sample in FIG. 3, with the addition of 20% methanol prior to heating and tryptic digestion.
FIG. 5 shows the data analysis from these mass spectrometry chromatograms indicating that a total of 77 proteins were commonly identified from these two separate preparations. In contrast, a total of 143 proteins were identified in the ammonium bicarbonate-only preparation that were not identified in the preparation with ammonium bicarbonate buffer in which 20% methanol was added to the buffer prior to tryptic digestion. In addition, a total of 134 unique proteins were identified in the 20% methanol/ammonium bicarbonate buffer that were not identified from the ammonium bicarbonate buffer alone preparation.
The present invention provides methods for multiplexing Liquid Tissue preparations derived from histopathologically processed tissue sections.
Previously, the present inventors have found that histopathologically processed biological samples can be heated in a reaction buffer, followed by protease treatment, to provide materials, herein termed Liquid Tissue preparations, that are rich in molecular information regarding the original biological sample. See U.S. Ser. No. 10/796,288, filed Mar. 10, 2004, the contents of which are incorporated by reference in their entirety.
As used herein and in the appended claims, the singular forms "a," "and," and "the" include plural reference unless the context clearly dictates otherwise. Thus, for example, reference to "a protein" is a reference to one or more proteins and includes equivalents thereof known to those skilled in the art, and so forth.
Histopathologically processed biological samples can include whole organisms, samples obtained from biopsy, diagnostic surgical pathology, tissue samples, body fluids (e.g., blood, plasma, serum, saliva, semen, cervical secretions, saliva, urine, tears, sweat, breast milk, and amniotic fluids), cellular or viral material, or any other biological sample that has been histopathologically processed.
Examples of histopathological processing of biological samples include, but are not limited, to: formalin fixation of whole organisms; formalin fixation of tissues or cells; formalin fixation/paraffin embedding of tissues or cells; and formalin fixation and/or paraffin embedding of tissue culture cells.
Histopathological processing typically occurs through the use of a formalin fixative. Formalin is used widely because it is relatively inexpensive, easy to handle, and once the formalin-fixed sample is embedded in paraffin the sample is stored easily. Additionally, formalin is often the fixative of choice because it preserves both tissue structure and cellular morphology. Although the exact mechanism may not be understood fully, fixation occurs by formalin-induced cross-linking of the proteins within the biological specimen. Due to these protein cross-links, formalin fixation has found wide success in the traditional microscopic analysis of histologic sections.
The sheer volume of formalin-fixed specimens cannot be overstated. For nearly the last one hundred years, biological specimens have been commonly fixed in formalin or formalin fixed/paraffin wax-embedded (FFPE) blocks. Universities and museums have vast archives of plants and animals that are formalin-fixed. Hospitals, in the course of diagnostic surgical pathology, have established large formalin-fixed collections that contain tissues from nearly every known disease in addition to normal, healthy tissue. Due to the need to retain these clinical tissue samples in case further testing is required, these archives around the world now contain millions of FFPE samples.
Liquid Tissue Preparations
The invention described herein provides for the use of Liquid Tissue preparations obtained from histopathologically processed biological samples. Generally, the Liquid Tissue preparations contain substantially all of the biomolecules contained within the sample, including but not limited to proteins, glycoproteins, nucleic acids (e.g., DNA, RNA), lipids, glycolipids, and cell organelle-derived molecules. As used herein, the term "protein" encompasses all proteins, including polypeptides, protein fragments, oligopeptides, and peptides containing two or more amino acids connected by peptide bonds.
The biomolecules contained within the Liquid Tissue preparation are useful as "analytes", either in a whole and intact form or and component thereof, if the biomolecule is detectable, such as by mass spectroscopy or by binding to a reagent of specific binding affinity. By way of non-limiting example, analytes useful herein include peptides generated by proteolytic digestion of proteins contained in the Liquid Tissue preparation.
In addition, the Liquid Tissue preparations described and used herein can be subjected to additional manipulations, such as fractionation by chromatography or other means, dilution, treatment with enzymes or other modifying agents.
Methods of Preparing Liquid Tissue Preparations
In general, Liquid Tissue preparations are generated by contacting all or a portion of a biological sample (e.g., a formalin-fixed tissue section) with a buffer solution. The sample in solution is heated for a time and at a temperature sufficient to negatively affect (e.g., reverse) the formalin-induced protein cross-links. For example, the heating is performed at a temperature of about 60° C. to about 100° C. (e.g., at about 65° C., 75° C., 80° C., 85° C., 90° C., 95° C., 98° C., 100° C., 102° C., or 105° C.) from about 30 seconds to about 24 hours or more (e.g., for 5, 10, 15, 30, 45 seconds, or 1, 2, 3, 4, 5, 10, 15, 30 or 45 minutes or 1, 2, 3, 4, 5, 7, 10, 14, 18, or 24 hours). Without being bound by any theory, the present inventors believe that the negative affect of temperature on the protein cross-links appears to involve some form of releasing, reversing, or partial modification of the cross-links. Generally, as used herein, the term "buffer" refers to a buffer which has a specific pH in the range of 1.0 to 9.0. Both specific pH and buffer types are selected based upon the required conditions, such as the proteolytic enzyme used. Both buffer type and specific pH requirements are known to those well versed in the arts. For additional details, see patent application U.S. Ser. No. 10/796,288.
The heated solution is then modified by adding at least one enzyme to the histopathologically processed biological sample. Enzymes include proteases, nucleases, glycosidases, lipases, phospholipases, phosphatases, and sulfatases. In a preferred embodiment, the enzyme is a proteolytic enzyme. Proteolytic enzymes are believed to augment the negative effect of heating on formalin-induced protein cross-links. One of skill in the art would recognize the time, temperature, and quantity of the enzyme sufficient to negatively affect the formalin-induced protein cross-links. Examples of proteolytic enzymes that are suitable for use in the present invention include but are not limited to trypsin, proteinase K, chymotrypsin, papain, pepsin, pronase, and endoproteinase Lys-C. Advantageously, the protease treatment is carried out following the heating step described above. The protease treatment is advantageously carried out at a temperature that is optimal for maximum activity of the protease, such as about 30° C. to about 60° C. Proteolytic enzyme treatment generally lasts for a period of about 1 minute to about 24 hours, such as 1, 2, 3, 5, 10, 15, 40 or 45 minutes, or 1, 2, 3, 4, 5, 10 18 or 24 hours.
If the sample is embedded in paraffin or some similar material, the paraffin may be removed by, for example, adding an organic solvent, heating, heating and adding a buffer comprising ammonium bicarbonate or Tris, and/or heating and adding an organic solvent. Advantageously, this step is carried out prior to the main heating step. If the sample is heated as part of the process to remove paraffin, the heating need only be brief, for example a few minutes. This brief heating advantageously may be repeated two or more times to ensure maximum removal of paraffin.
At any stage the sample may be mechanically disrupted by, for example, manual homogenization, vortexing, and/or physical mixing. The simultaneous multiple Liquid Tissue preparations produced by these methods are subjected to a wide variety of biochemical assays including arrays, protein arrays, and mass spectrometry.
In one embodiment of the current invention, the Liquid Tissue preparation is fractionated into distinct and separate biomolecules that may be collected separately. Examples of biomolecule fractions that can be collected include but are not limited to protein, glycoproteins, nucleic acids (e.g., DNA, RNA), glycolipids, and lipids. Fractionation techniques are well known in the arts and include but are not limited to, spin column fractionation, immunoprecipitation, gradient centrifugation, HPLC and drip column fractionation. Other fractionation methods are well known in the art.
In another embodiment of the current invention, the Liquid Tissue preparation is modified by the addition of one or more detergents, including for example Nonidet-P-40, SDS, Tween-20, Triton-X, and sodium deoxycholate. The detergent is added prior to the protease treatment step (before or after heating), in which case the nature of the detergent and its concentration is selected so as to not substantially inhibit the activity of the protease. Alternatively, the detergent is added after addition of the protease.
Multiplexing of Liquid Tissue Preparations
One embodiment of the invention provides for the generation of a plurality of multiplexed Liquid Tissue preparations from a single histopathologically processed biological sample where each of the individual multiplexed preparations consists of distinctly different biochemical properties such that subsequent analysis of all Liquid Tissue preparations from a single histopathologically processed sample render more experimental data about the biomolecules in the histopathologically processed biological sample than a single Liquid Tissue preparation can render by itself. The combination of a plurality of multiplexed Liquid Tissue preparations can be used to generate a tissue proteome, which is the complete collection of proteins found in a particular tissue under a particular set of conditions, such as the presence of a disease. Each individual Liquid Tissue preparation forms a representative subset library of the total library of biomolecules (the tissue proteome) that exist in that histopathologically processed biological sample.
Use of the Lysates
The method described herein is particularly useful because it can be used to obtain a plurality of multiplexed multi-use biomolecule lysates from a single histopathologically processed biological sample where each lysate is capable of being used with numerous experimental and diagnostic techniques to generate complementary information about the histopathologically processed biological sample, thereby providing new uses for the histopathologically processed archive. Examples of techniques that the plurality of preparations can be used with include but are not limited to are chromatography, protein arrays, Western blotting, immunoprecipitation, affinity columns, alternative splicing assays, and high throughput assays such as but not limited to one- and two-dimensional polyacrylamide gel electrophoresis (2D-PAGE), serial analysis of gene expression (SAGE), high performance liquid chromatography (HPLC), fast protein liquid chromatography (FPLC), matrix-assisted laser desorption/ionisation-time of flight mass spectrometry (MALDI-TOF), SELDI mass spectrometry, liquid chromatography, mass spectrometry, and ELISA assays. The skilled artisan will recognize that the lysates produced by the methods of the invention also may be used in a wide variety of additional assays.
The recent completion of the Human Genome Project, in addition to spurring dramatic advances in the field of genomics and proteomics, has demonstrated the vast potential of high throughput assays. Proteomics attempts to identify and quantify proteins in biological samples and is now attempting to determine the functions of all proteins in an organism, organ, or organelle, and how these proteins vary with time and physiological state.
Analyte Detection and Quantitation
Detection of one or more analytes is accomplished by any means known to those skilled in the art. A preferred detection means is mass spectroscopy, such as matrix-assisted laser desorption/ionization-time of flight mass spectrometry (MALDI-TOF), liquid chromatography electrospray ionization tandem mass spectrometry (LC-ESI-MS/MS), or surface enhanced laser desorption ionization (SELDI) mass spectrometry. Mass spectroscopic analyses are described in greater detail below.
Exemplary analytes are provided in Table 1.
Other detection means include but are not limited to are column chromatography, protein arrays, Western blotting, immunoprecipitation, affinity columns, alternative splicing assays, mutation analysis, nucleic acid amplification (for example PCR, LCR, and T7-based RNA amplification), labeled probes for microarray analysis, RFLP analysis, Southern blotting, and high-through put assays such as but not limited to one- and two-dimensional polyacrylamide gel electrophoresis (2D-PAGE), serial analysis of gene expression (SAGE), HPLC, FPLC, liquid chromatography, ELISA assays, Quantitative RT-PCR, Single Nucleotide Polymorphism detection, genotyping and protein and nucleic acid sequencing.

J Histochem Cytochem. 1998 46 (3): 397-403.
When the analyte of interest is a protein or peptide, the Liquid Tissue preparation is generally in a soluble liquid form and is representative of the total protein content of the cells procured from the starting histopathologically processed biological sample. The preparation is used in any number of protein identification, analysis and expression assays described herein or known to the skilled practitioner.
When the analyte of interest is DNA, the Liquid Tissue preparation is in a soluble liquid form and is representative of the total DNA content of the cells procured from the starting histopathologically processed biological sample. The DNA extract can be placed in any number of DNA and/or RNA gene identification analyses and monitoring assays designed to determine variations in DNA including but not limited to the analysis of gene structure, genetic variability, single nucleotide polymorphisms and mutation analyses.
When the analyte of interest is RNA, the Liquid Tissue preparation is in a soluble liquid form and is representative of the total RNA content of the cells procured from the starting histopathologically processed biological sample. The RNA extract can be placed in any number of RNA and/or gene identification analysis and gene expression analysis and quantitative RT-PCR analysis
In certain embodiments it is useful to quantitate the detected analytes. This quantitation is performed by, e.g., isotopic labeling of the proteins; methods for isotope labelling include SILAC (stable isotope labelling with amino acids in cell culture), ICAT (isotope coded affinity tagging), and ITRAQ (isotope tags for relative and absolute quantitation). Alternatively, quantitation is performed by the use of AQUA peptides (See, Stemmann et al., Dual inhibition of sister chromatid separation at metaphase, Cell 107: 715-726 (2001)).
In certain embodiments the analyte detected in the Liquid Tissue preparation is compared with a reference analyte. A reference analyte is any analyte obtained from a subject known to have or not have the disease, condition, or syndrome. In certain embodiments, a reference analyte comprises a database.
Mass Spectrometry Assays
A specific example of a proteomic assay capable of generating information about protein expression patterns is mass spectrometry. Mass spectrometry can be conducted in a highly parallel manner, is highly sensitive, and is capable of generating an enormous amount of data in a single experiment. The data generated by a single mass spectrometry analysis of a single Liquid Tissue protein preparation is so voluminous that specialized computer software is required to read and analyze the data that is generated.
In order to significantly link a single candidate marker to any disease, a large number of cases must be screened to generate definitive correlations. However, obtaining enough biological samples with known disease outcomes in a frozen or stable and storable state that is not chemically fixed is a limiting factor. A possible solution to this limitation would be the use of the worldwide archive of diseased tissue and cells. The methods of the current invention are particularly useful because a plurality of multi-use Liquid Tissue preparations from a single histopathologically processed biological sample allows collection of large amounts of experimental data from a single sample in a high throughput fashion by mass spectrometry.
In one type of mass spectrometry analysis, a single Liquid Tissue preparation is subjected to one of many forms of chromatography where each form is directly attached to a high-resolution mass spectrometer. As fractions come off the chromatography column they are instantly analyzed by the mass spectrometer by nanospray technology. Sophisticated computer programs translate all the ion information obtained by nanospray analysis of every chromatography fraction into data containing identification of as many peptides as the instrument is able to resolve. Collecting peptide identification about each and every chromatography fraction, and pooling these data can positively identify hundreds to thousands of individual peptides from the starting Liquid Tissue preparation, which translates to the ability to positively identify expression of hundreds of suspected biomarkers directly from a single Liquid Tissue preparation from a single formalin fixed archival tissue. The method of this invention is to prepare a plurality of Liquid Tissue preparations from a single cellular region of sufficient cellular homogeneity from a single formalin fixed archival tissue sample and perform the type of mass spectrometry described herein, where each of the Liquid Tissue preparations is composed of different and unique biochemical properties so that when analyzed by mass spectrometry a different and unique subset of peptides are positively identified from each and every individual Liquid Tissue preparations.
Thus, the present invention provides the ability will result in the ability to combine data from many different multiplexed Liquid Tissue preparations from the same cellular region of a single formalin fixed tissue sample rendering the combined identification on many more proteins than if a single Liquid Tissue preparation were analyzed only once. In this way, thousands (and possibly tens of thousands) of suspected biomarkers can be identified, discovered, and analyzed in a single experiment directly from a single cellular region obtained from a single formalin fixed archival tissue. By performing this multiplex strategy for a single formalin fixed tissue sample across many formalin fixed tissue samples of the same disease and pathology, it becomes possible to link thousands to tens of thousands of potential biomarkers to a specific histologically identified disease process. This translates to providing statistical significance in the quest to link specific proteins to the pathological manifestation of the progression of diseases such as cancer and neurological disorders.
Specific mass spectrometry instruments and data analysis computer programs to perform these experiments are commercially provided by a number of vendors and instruments manufacturers. These companies include ThermoElectron (San Jose, Calif.), Bruker Daltonics (Billerica, Mass.), and Applied Biosystems (Foster City, Calif.).
As used herein, the term "nanospray" also refers to the terms "ionspray" and "electrospray". All of these terms can be used interchangeably. As used herein, the term "sufficient homogeneity" refers to a population of tissues or cells that possess similar pathological characteristics or traits based on selection criteria. An example of selection criteria includes but is not limited to histopathological selection criteria that are well known in the relevant arts. Examples of methods of "obtaining" a biological sample include, but are not limited to, using a manual core punch, tissue punch, tissue scrape, laser-based microdissection, and other techniques known to one of skill in the art The amount of biological sample required to carry out the invention will vary depending on the specific type of assay being conducted on the sample.
Liquid Tissue Arrays
In the present invention of procuring a plurality of different biomolecular preparations from a single histopathologically processed sample to achieve complementary and additive data about the histopathologically processed sample, each lysate of biomolecules forms a representative library of specific biomolecules that directly reflects the status of a subset of biomolecules as they previously resided in the pathologically processed biological sample.
The resulting procured biomolecules can be placed in an arrayed format for the simultaneous biochemical analysis of multiple Liquid Tissue preparations obtained from a single histopathologically processed sample or multiple and different histopathologically processed biological samples to achieve a high throughput biochemical assay format for the molecular analysis and profiling of pathologically processed biological samples. One example of such a high throughput array assay format would be the development of a Liquid Tissue protein array such that tissue protein lysates derived from the processed histopathological tissue and procured as stated above are arrayed in an ordered and defined pattern as small spots of protein on a solid support substrate, where each spot is a representative library of the expressed proteins, and characteristics of those expressed proteins, that resided in the pathologically processed biological sample, and that when assayed by a number of various biochemical protein analysis formats, such as immuno-based protein identification binding assays, do directly reflect the expression pattern and characteristic of the proteins as they relate to the pathology and histology of the pathologically processed biological sample from which the proteins were procured.
When the biomolecule is a protein or peptide, the plurality of protein or peptide extracts is in a soluble liquid form where each preparation contains and is representative of a subset of the total protein content of the cells procured from the starting histopathologically processed biological sample. The multitude of Liquid Tissue protein extracts can be placed in any number of protein identification, analysis, and expression monitoring assays including, but not limited to, mass spectrometry and protein microarrays that contain representative libraries of proteins from pathologically and histologically defined populations of histopathologically processed biological sample and as these analyses relate to the histology, disease state, and pathology of the histopathologically processed biological sample.
Multiple Liquid Tissue preparations obtained from multiple different histopathologically processed biological samples can be placed in an array format. A specific example of a high-throughput assay is the protein array. Protein arrays are highly parallel (multiplexed) and can be conducted in miniature (microarray). Protein arrays are quick, usually automated, highly sensitive, and capable of generating an enormous amount of data in a single experiment. The protein array is essentially a miniaturized version of the familiar ELISA or dot blotting immunoassay. Similar to ELISA and dot blots, protein array results are usually obtained using optical detection methods, for example fluorescent detection. The data generated by a single protein array experiment often is so voluminous that specialized computer software is useful to read and analyze the data that is generated.
In one type of protein array analysis, specific capture reagents of known binding affinity, such as antibodies, are immobilized or spotted onto a support surface in a known positional manner, thus forming the protein array. The Liquid Tissue preparation is then contacted with the protein array. Because the immobilized binding proteins on the support surface have a specific affinity for an individual protein or marker, protein arrays are able to detect target molecules or marker proteins in the Liquid Tissue preparation. By immobilizing the specific capture reagents in known locations on the support surface, protein identification and the presence of marker proteins can be determined by x, y positional information. In addition, since differences in protein levels within complex samples can be easily measured, accurate quantitative differential analysis can also be performed. Detection is achieved through a number of methods known to those well versed in the art. Examples include but are not limited to: secondary antibodies in sandwich assays, direct labeling of analytes, dual color labeling, mass spectrometry, surface plasmon resonance, and atomic force microscopy.
An alternative type of protein array analysis places tissue/cell lysates in an arrayed format, for example on a solid support. Multiple lysates from different samples may be arrayed on a single surface in a positionally identifiable manner. Reagents of known binding specificity, such as antibodies, that bind to target biomolecules or markers are then added. The main difference between the two major types of array analyses described herein is that in the first type of protein array, the expression of many different proteins across a single source of protein (a single cancer tissue for example) can be determined. In contrast, by the other type of protein array analysis, one can assay for the expression of one protein at a time across many different sources of protein (many different cases of cancer tissues for example). The lysate may be fractionated prior to immobilization on the array, and protein containing fractions of the lysates may be used to prepare the array. The skilled artisan will recognize also that other fractions of the lysates can be used to prepare arrays. For example, DNA and/or RNA containing fractions can be immobilized on suitable surfaces to prepare nucleic acid arrays.
Specific reagents of known binding affinity in protein arrays advantageously are antibodies or antibody fragments, but may also be single domain antibodies, engineered scaffolds, peptides, nucleic acid aptamers, small molecules such as drugs, for example, protein ligands, or other specific binding proteins known in the relevant art. Antibodies may be either polyclonal or monoclonal, or a portion or fragment of an antibody capable of binding antigenic sites, and are available from the usual commercial sources such as Sigma-Aldrich Co. (St. Louis, Mo.).
Protein array support surfaces include but are not limited to glass (such as slides), silicon, porous silicon, nylon, PVDF or nitrocellulose membranes and the like, or beads and are available from a variety of commercial sources. Alternatively, specialized chips have been developed for protein assays and are commercially available from, for example, Biotrove (Woburn, Mass.), Zyomyx (Hayward, Calif.) and Pontilliste (Mountain View, Calif.).
Specific capture reagents or Liquid Tissue preparations are spotted or immobilized onto the support surface by a number of techniques familiar to those knowledgeable in the arts. Examples include, but are not limited to, robotic contact printing, robotic non-contact printing, ink jetting, and piezoelectric spotting. If the capture reagent is a polymer that may be synthesized on a solid support, such as a nucleic acid, the capture reagent may be prepared directly on the support by, for example, photolithography. A number of automated commercial spotters are available from, for example, Packard Bioscience (Meriden, Conn.) and manual spotting equipment also is commercially available from, e.g. V & P Scientific (San Diego, Calif.).
The present invention includes articles of manufacture, such as "kits". Such kits will typically be specially adapted to contain in close compartmentalization each container holding a component useful in carrying out the preparation of the multitude of Liquid Tissue preparations according to the methods and compositions taught herein.
